Subject: [PATCH] Remove deprecated APIs to get the total and free memory
 available to vmm.ko.

These APIs were relevant when memory for virtual machine allocation was
hard partitioned away from the rest of the system but that is no longer
the case. The sysctls that provided this information were garbage collected
a while back.
